=============================================.
SRT.
Minkowski spacetime was born in SRT.
In SRT gravity is absent.
It means Minkowski spacetime does not has gravity and this
spacetime is Pseudo-Euclid's flat spacetime.
Minkowski spacetime is absolute conception.
2.
GRT.
When Einstein put mass into Minkowski spacetime
it is curved.
When Friedman put time into Minkowski spacetime
it is curved too.
In GRT the "spacetime curves".
If Minkowski spacetime is curved it isn’t more Minkowski spacetime.
( you wrote too: The curvature is gravity.)

This “Minkowski spacetime” is now Gravity space.
Gravity space has 3-D + time.
Gravity space (3-D + time) is relative conception..
